net: tc35815: Explicitly check NET_IP_ALIGN is not zero in tc35815_rx
clang warns:
drivers/net/ethernet/toshiba/tc35815.c:1507:30: warning: use of logical
'&&' with constant operand [-Wconstant-logical-operand]
if (!HAVE_DMA_RXALIGN(lp) && NET_IP_ALIGN)
^ ~~~~~~~~~~~~
drivers/net/ethernet/toshiba/tc35815.c:1507:30: note: use '&' for a
bitwise operation
if (!HAVE_DMA_RXALIGN(lp) && NET_IP_ALIGN)
^~
&
drivers/net/ethernet/toshiba/tc35815.c:1507:30: note: remove constant to
silence this warning
if (!HAVE_DMA_RXALIGN(lp) && NET_IP_ALIGN)
~^~~~~~~~~~~~~~~
1 warning generated.
Explicitly check that NET_IP_ALIGN is not zero, which matches how this
is checked in other parts of the tree. Because NET_IP_ALIGN is a build
time constant, this check will be constant folded away during
optimization.
